UPHOLSTERING-SPRING.

SPECIFICATION forming part of Letters Patent No. 232,462, dated September 21, 1880.

Application filed May 18, 1880.

To all whom it may concern Be it known that I, THOMAS J. CORR, of Hoopeston, in the county of Vermillion, and in the State ofIllinois, have invented certain new and useful Improvements in Upholstering- Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of referto once marked thereon, making a part of this specification.

This invention relates to certain improvements in springs for upholstering; and it consists of a. vertical spiral spring with a horil5 zontal base consisting of radiating arms and a vertical stem or postat the center of the base extending through a loop at the lower coil of the spring, whereby the leverage or pressure is equally distributed between the ends of the arms forming the base, the spring, base, and central stem or post being all formed of one and the same piece of wire.

In the drawings, Figure 1 represents a perspective view of my improved spring entire,

2 5 and Fig. 2 a perspective view of the base broken off.

The letter 0 indicates the spring proper, which consists of a spiral coil gradually decreasing in diameter from top to bottom, where the wire is bent into a loop, 0, then bentlaterally and horizontally a proper distance, and

(Model) then back again to the spring, then laterally and horizontally at right angles, and then back again, as before, and so on till the four radiating arms B of the base are formed. The wire is then bent up vertically through the loop 0, forming the central post, A, as clearly shown in Fig. 2 of the drawings in detail.

The outer ends of theradiatin g arms of the base thus constructed form points of attach- 4o ment for securing the base to the slab or frame of an article of furniture, the securing screws or staples being passed between the sides of the arms at the ends.

Having thus fully described my invention, 5 what I claim, and desire to secure by Letters Patent, is-

An upholstering spring consisting of a vertical spiral coil having a horizontal base consisting of radiating arms, and a vertical 5o stem or post at the center of the arms extending through a loop at the lower part of the coil, the said coil, base, and center pin or post being formed of one and the same piece of wire, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of May, 1880.
